1. 2x+5(6x-9)=179
2. -40=6x-5(-4x-18)
solve for X
Answers
Answer:
1. x = 7
2. x = -5
Step-by-step explanation:
1. Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation: 2*x+5*(6*x-9)-(179)=0
Pull out like factors 6x - 9 = 3 • (2x - 3)
(2x + 15 • (2x - 3)) - 179 = 0
Pull out like factors: 32x - 224 = 32 • (x - 7)
Solve: x-7 = 0
Add 7 to both sides of the equation = 7
2. Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation: -40-(6*x-5*(-4*x-18))=0
Pull out like factors: -4x - 18 = -2 • (2x + 9)
-40 - (6x - -10 • (2x + 9)) = 0
Pull out like factors: -26x - 130 = -26 • (x + 5)
-26 • (x + 5) = 0
Solve: x+5 = 0
Subtract 5 from both sides of the equation: x = -5

Answers
Answer:
A cardioid
Step-by-step explanation:
A cardioid is a curve in the shape of a heart traced by a point on the circumference of a circle as it rolls around a fixed circle of the same radius.
The equation of vertical cardioid is [tex]r=a[/tex] ± [tex]a\sin \theta[/tex]
Given the polar curve is [tex]r=[/tex] [tex]1+[/tex] 4 [tex]\sin \theta[/tex]
This is an equation of vertical cardioid.
So, it represents a cardioid.

Step-by-step explanation:
From the question, we are informed that Rachael receives 4,300 frequent-flier miles for her first round trip and 1,900 frequent-flier miles for each additional round-trip.
The number of frequent-flier miles she will she have after 5 round-trips will be:

Joe can run 12 miles in 125 minutes. How many miles can he run in 230 minutes? (solve and explain the steps)
Answers
Answer:
Joe will run 22.08 miles in 230 minutes.
Step-by-step explanation:
Given that Joe can run 12 miles in 125 minutes.so Joe running the miles in 1 minute is = 12/125 = 0.096 miles
unit rate = 0.096 miles/per minuteAs Joe runs 0.096 miles in one minute.
Thus, in 230 minutes, Joe will run = 0.096 × 230 = 22.08 miles
Therefore, Joe will run 22.08 miles in 230 minutes.

Step-by-step explanation:
Given
[tex]a = 2[/tex]
[tex]b = 4[/tex]
c = hypotenuse
Required
Find c
Using Pythagoras theorem, we have:
[tex]c^2 = a^2 + b^2[/tex]
Substitute values for a and b
[tex]c^2 = 2^2 + 4^2[/tex]
[tex]c^2 = 4 + 16[/tex]
[tex]c^2 = 20[/tex]
Take square roots of both sides:
[tex]c = \sqrt{20[/tex]
Express 20 as 4 * 5
[tex]c = \sqrt{4 * 5[/tex]
Split surd
[tex]c = \sqrt{4} * \sqrt{5[/tex]
Take square root of 4
[tex]c = 2 * \sqrt{5[/tex]
[tex]c = 2\sqrt{5[/tex]
